2 Claims. (01. 179-100) My invention relates to desk telephones which sothat the same may be accessible at any time are adapted for use with thecradle type or hand by just removing the cover. The cover is prefsettelephone receiver and transmitter. erably made of a suitable insulatingcompound,

It is the principal purpose of this invention to such for example, asthe synthetic resin com- 5 provide novel means of mounting the telephonepounds.

The operating mechanism of I theringer set. 1 forms no part of the present invention, so it will Myinvention contemplates further the pronot be described.

As shown, the bosses The dial mechanism is indicatedgenerally by 60 are secured on the posts by suitable screws.

The upper end of this bar '48 restsupon a 66ily removable without disturbing the equipment shelf 49 which is part ofthe member 3| and is pressed downwardly by a suitable spring 50 carriedby the cover. The bar 48 is pivoted by means of the slot uprights 5|, itbeing understood that there is one upright at each side in which theextension 52 of the bar is both slidable and rotatable, the uprightsbeing slotted with a slot 53 as shown. The cover thus can be lifted offand the dial will remain in place, then when the cover has been liftedOK, the dial mech anism can be folded back into the dotted line positionshown in Fig. 3 to permit ready access to the wiring on the backthereof. The induction coil which is housed in the base at 55 and thecondenser 58 are fixed on the base so that all of the parts of thetelephone are readily accessible when the cover I2 is removed. Thecondensers 56 are held down by suitable straps such as shown at 51.

From the above description it is believed that the construction andadvantages of this device will be clear to those skilled in the art andwhile I have shown one specific form of my invention, it is obviousthatvarious modifications may be made without departing from the spiritof the invention.

Having thus described my invention, what I claim is new and desire toclaim by Letters Patent is: I

1. A desk telephone set having in combination a base, a ringingmechanism mounted on said base adjacentone side edge thereof, a dialswingingly secured to said base at the side opposite said ringingmechanism and projecting upwardly over the base toward the centerthereof, a hook switch mechanism mounted on said base between the dialand ringing mechanism mountings, said hook switch mechanism beingprovided with a shelf upon which the upper end of the dial is supported,and a cover over said mechanism having an opening for said dial andhaving projections formedthereon for supporting a hand set, said dialbeing also slidable with respect to the base whereby to permit itsmovement with the cover as the cover is removed from the base.

2.
